REVERSIBLE ELECTRIC VAPORIZER Application filed January 24, 1930.

My invention relates to Vaporizers and refers more particularly to a reversible electric vaporizer within which a predetermined temperature may be maintained.

One object of my invention is to provide a vaporizer formed and operable to prevent the formation of carbon therein.

Another object of my invention is to provide a vaporizer with the object in view of doing away with the expensive furnace structure ordinarily required for this work.

A further object of my invention is to provide a vaporizer that is reversible.

A still further object of my invention is to provide a vaporizer wherein the liquid to be volatilized is forced to flow on flat surfaces over a series of superimposed ste 5.

One of the valuable features 0 my invention is to provide an electrically operated vaporizer that can be operated under pressure.

Another of the valuable features of my invention is to provide a system for controlling the vapor pressure by means of a multiple of throttle valves.

5 Still another valuable feature of my invention is to provide a vaporizer wherein liquids are vaporized while flowing over superimposed stepped surfaces, the temperature of which is controlled electrically and an adjustable electric heating means controlling the temperature of the stepped s aces.

I attain these results prefera bly by the means illustrated in the accompanying drawings, wherein similar'numerals refer to like parts throughout the several views, in

which Figure 1 is a diagrammatic view of the vaporizer connected to apparatus that is associated with it. v 3

Figure 2 is a diagrammatic view of'the vaporizer illustrating in detail its construction and parts. I I

Figure '3is a section taken on lines 33 of Figure 2.

45 The vaporizer 1, is comprised of a rectangular casing 2, provided with pivots 3 and 4 and within this casing extending cross-wise, as shown in Figures 2 and 3, is a double partition formed to provide sto s 5, 6, 7, 8, 9, 10

50 and 11, as clearly shown in igure2, and this Serial No. 423,163.

partition is made in two parts, the part 12 separated from the part 13, so that the insulation 14 and 15 may be placed in such a way that the lead 16, which is coiled at 17, 18, 19, 20, 21, 22 and 23 will be insulated from the partition and easing.

One end of this lead 16 is connected to a coil 24,, that is within a removable holder 25, and insulated therein by means of the insulation 26, this holder being attached to the part 2 by means of the bolts 27 and 28.

The end 29 of the lead 16is connected to a coil'30, that is within a holder 31, that is insulated by insulation 32, and held to the part 2 byineansv of the bolts 33 and 34.

The lead 29 is connected by the conductor '41 to a ring 42 which engages with a brush 43 connected by "a conductor 44 to a rheostat 45 and the rheostat is connected to the coil 39 by means of the conductor 46.

One end of the resistor 24 is connected to the coil 39 by the conductor. 38 through the brush 37, ring 36 and conductor 35 and the other end of this coil is connected by the conductor to the rheostat 51 and this rheostat is also connected by the conductor 52 to the conductor 46 which is connected with the coil The resistor 30 is connected by the conductor 53 to a. ring 54 which engages with a brush 55 connected by the conductor 56 to a rheostat 57, and this rheostat is connected by the con ductor 58 to the conductor 52 that is connected to the coil 39 by means of the conductor 46.

It is obviousthat the rheostats 45, 51 and 57 are adapted to control the amount of current supplied to the coils 17 to 23 inclusive, and also control the current passing through the coils 24 and 30.

The primary coil 59 ofthe transformer 40 is connected to a switch 60 and this switch is connected by the conductors 61 and 62 to a thermostat 63, which may be adjusted to operate this switch 60 at any desirable temperature, so as to control the heat within the s ace 64 and this switch 60 is also connecte b means of the leads 65 and 66 to a thermostat 67 that is adapted to control the temperature in the space 68 within the vaporizer.

The opposite ends of the casing 2 are provided with pipe connections 69 and 70, that are located at the center of the device.

One end of this casing is supplied with an inlet 71, connected to a cross pipe 72, providedwith a series of holes 73, adapted to spray the liquid passing through the pipe in the direction shown in Figure 2, and the other end of this casing is provided with an inlet 74, connected to a cross pipe 75, provided with holes 76 that are adapted to spray liquid in a similar manner as shown by the pipe 72.

The outlet 69 is utilized as an outlet for the vapor that may be formed Within the casing in the position shown in Figure 2 and when this outlet is used to carry off the vapor, the outlet 7 0 may be closed by means of the cap shown by the dotted lines .77, and when this device is reversed, the outlet 70 will be used to carry away the vapor and the outlet 69 closed. 1

In the position shown in Figure 2, the inlet 71 is adapted to carry material to be vaporized and the inlet 74 is closed as shown by the dotted lines 78, and in the position shown in Figure 1, the outlet 79 is adapted to carry away the material that is not vaporized and the side outlet 80 may be closed by means of the plate like 81, and it is obvious that an asbestos sheet 82 may be placed as shown in Figure 2 to facilitate the operation and control .of the device and when the still is reversed, the asbestos sheet maybe removed anld a similar one placed on the opposite s1 e.

The pivots 3 and 4 are mounted in suitable mountings like 83 and 84, shown in Figure 1, and the outlet 69 is connected to a pipe 85 provided with a valve 86, that is connected to a vapor chamber 87 provided with a drain valve 88.

The outlet 89 of this chamber 87 is connected to a dephlegmator 90, provided with baflles 91, and this dephlegmator is connected by the pipe 92, containing a valve 93, to a condensor 94.

This condensor 94 is connected by the pipe 95, carrying a valve 96, to a storage tank 97, that is provided with gauges 98 and 99, and a drain outlet with a valve 100, and a vapor outlet with avalve 101.

The bottom of the dephlegmator is connected-by means of the pipe 102, carrying a valve 103, to a crude oil or petroleum storage tank 104, having a manhole 105, and an inlet pipe 106, having a valve 107, and an indicating gauge 108.

The bottom of this tank 104 isconnected by means of the pipe 109, containing a valve 110 to a swinging elbow 111, that may be connected to the inlet 71, or when the vaporizer is reversed, it maybe swung around and connected to the inlet 74 and when this is done, the pipe 85 may be connected to the inlet 70.

This vaporizer isprovided with manholes 112 and 113 on opposite ends, so that repairs may be made to the interior of the vaporizer.

Furthermore, it is obvious that in distilling liquids, that may contain sticky or viscous sediments, that in reversing the vaporizer periodically the sticky or viscous material could be drained from one side of the vaporizer while the other side is vaporizing fresh material.

By handling light hydrocarbons, in this manner, it is posible to obtain in one operation a complete fractionation of the hydrocarbons and to control this fractionating pressure so as to obtain any of the desired fractionates very easily.

The inside of the vaporizer is preferably constructed so as to provide a highly polished surface or provide with any suitable means for refracting the heat therein toward the center of the vaporizer, the object being to.

increase the efliciency of the vaporizer and to conserve heat loss through radiation and heat insulating material may be placed on the outside of the still, if desired.

Having thus illustrated and described the preferred embodiment of my invention, I do not wish to limit myself to the exact con-' struction or arrangement of parts shown, since it'is evident that modifications may be made therein, without departin from the spirit of the invention, or scope o the claims.
